I understand. My question was more your advice to someone whose skills are light going out and buying a 30 ft yacht thinking they can sail off when TSHTF and be fine at sea for 180 days.
If folks are infirm or suffer motion sickness they can’t get over, then sailing is out. Otherwise, if you can learn to ride a bike, you can learn to sail.
But the utility of the sailboat escape pod option is not only for pulling thousand-mile voyages. A sailboat allows you to coast-hop from a really horrible location to a better one. One state might be reduced to Somalia or Rwanda, while another might be relatively safe. Forget driving, you will just get trapped in fatal gridlock. A small plane or a sailboat will allow you to bypass the gridlock, roadblocks and ambuses.
Read about John Guzzwell, who sailed a home-made 20 footer from California to Australia to return to his girlfriend. Or many other similar stories. It’s viable, if you are healthy enough for hiking and camping and agile enough to ride a bike, you CAN sail. As long as you are not chronically seasick, which some folks are.
